Scientists have discovered a giant sequoia still smoldering in California’s Sequoia national forest, months after wildfires tore through the region last August. The tree was found, charred but still standing, by researchers in the lower part of the national forest this week. While turning down a sharp switchback on the trail, a member of Sequoia’s fire ecology and research team spotted a plume of smoke in the ravine below. Using a long camera lens, the team tracked the smoke to a single giant sequoia, standing in the burn area from last year’s Castle fire. The enormous tree, which has probably stood for hundreds if not thousands of years, looked like a chimney spouting smoke in the middle of the blackened forest.
